DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
TYMLOS is a drug for the treatment of postmenopausal women with osteoporosis who are at high risk for bone fracture.
How is this drug used?
TYMLOS is an injection that is administered once a day under the skin (subcutaneously).
What are the benefits of this drug?
Patients who received TYMLOS had fewer new bone fractures compared to placebo.
Were there any differences in how well the drug worked in clinical trials among sex, race and age?
- Sex: All patients in the trial were women; therefore, differences in how well the drug worked between sexes could not be determined.
- Race: Most of the patients were White. Differences in bone fractures among races could not be determined because of the small number of patients in other races.
- Age: TYMLOS worked similarly in all age groups studied.
What are the possible side effects?
TYMLOS may increase the risk for bone cancer. This is based on animal studies only.
Serious side effects of TYMLOS include a drop in blood pressure upon standing and an increase in blood and urine calcium that may increase the chance of developing kidney stones.
The most common side effects of TYMLOS are an increase in urine calcium, dizziness, nausea, headache, fast heartbeat, fatigue, and upper belly pain.
Were there any differences in side effects among sex, race and age?
- Sex: All patients in the trial were women; therefore, differences in side effects between sexes could not be determined.
- Race: Most of the patients were White. Differences in side effects among races could not be determined because of the small number of patients in other races.
- Age: The occurrence of side effects was similar in all age groups studied.
WHO WAS IN THE CLINICAL TRIALS?
Who participated in the clinical trials?
The FDA approved TYMLOS based on evidence from one clinical trial of 1645 postmenopausal women with osteoporosis. The trial was conducted in North and South America, Europe and Asia.

How were the trials designed?
There was one trial that evaluated the benefit and side effects of TYMLOS. All patients were women with osteoporosis who took daily calcium and vitamin D supplements.
In the trial, patients were randomly assigned to receive either TYMLOS or placebo injection under the belly skin once daily, for 18 months. Neither the patients nor the health care providers knew which treatment was being given until after the trial was completed.
The benefit of TYMLOS was evaluated by measuring the occurrence of new spine fractures in patients treated with TYMLOS in comparison to placebo during 18 months of treatment.
After the benefit was measured, some of the patients who were previously treated with TYMLOS and some who were previously treated with placebo received alendronate (another approved medication for postmenopausal women with osteoporosis) with calcium and vitamin D supplements for 6 months. The benefit of TYMLOS was further evaluated by measuring the occurrence of new spine fractures up until this 6 month time point (a total of 25 months since first starting TYMLOS or placebo).
GLOSSARY
CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
